Safe Haven Sunday was a day set aside by the Diocese wherein all parishes were encouraged to preach and teach about the evils of pornography, the damage it does, and how to avoid or escape its clutches. This is a sermon given by a parish priest to his flock. Books and prayer cards were part of the whole teaching. Covenant Eyes was instrumental in producing these helpful handouts and can be of further assistance by contacting them. A web search should lead you in the right direction.
